How to increase the volume of Bluetooth headphones Xiaomi: proven methods

You bought new Xiaomi Bluetooth headphones, but their volume leaves much to be desired? This problem is familiar to many owners of wireless headsets - from budget Redmi Buds to flagship Xiaomi FlipBuds Pro. The reasons can lie in the limitations of the manufacturer (included in the firmware of the smartphone or the headphones themselves), and incorrect settings of the device.

In this article, we'll look at 7 working ways to turn up the volume, including hidden MIUI settings, engineering menus, third-party apps, and even hardware solutions. Importantly, not all methods are equally safe — some can affect sound quality or shorten the life of speakers. We've noted the risks in each section so you can choose the best option.

Let's start with the simplest and safest ways that don't require root rights or deep technical knowledge, and if you're an iPhone user, some of the methods (like ADB) won't work, but there are alternatives.

1. Checking basic settings: what you might have missed

Before you go to the engineering menu or install third-party apps, make sure that the problem is not in the obvious settings. Often users overlook simple settings that limit volume.

Let’s start with the Bluetooth settings on the smartphone:

• 📱 Open the Settings. → Bluetooth and find your headphones in the list of connected devices.
• 🔊 Click on the gear icon next to the headphones name and check the Media Volume slider – it should be at maximum.
• 🎧 Some models (such as Xiaomi Buds 4 Pro) have a separate Mi Earphones app – there may be a volume limit.

Check the sound settings in MIUI:

• 🔈 Go to Settings. → Sound and vibration → Loudness.
• 📊 Make sure that the Multimedia slider (not the “Ring” or “Alarm”) is set to maximum.
• 🚫 Turn off the Safe Volume function (if it is active) – it automatically lowers the sound level.

💡

If after connecting the headphones volume drops sharply, try to turn off the function "Absolute Volume" in the developer settings (we will talk about it below).

Keep in mind the physical buttons on the headphones themselves: some models (like the Redmi AirDots 3) have a limit on the maximum volume that is reset once you reconnect.

1. Turn off the headphones from the smartphone.
2. Press the power button on the headphones for 10 seconds (until the indicator blinks).
3. Reconnect and check the volume.

2 Developer Settings: Hidden MIUI Limits

Xiaomi (and other manufacturers) artificially limits the maximum volume via Bluetooth to protect users’ hearing, which can be circumvented through the developer menu – it is on all smartphones running MIUI (including POCO and Black Shark).

How to turn on the developer mode:

1. Go to Settings. → The phone.
2. Press 7 times in a row on the item "Version" MIUI" (A notice will appear saying, “You have become a developer").
3. Return to the main settings menu – there will be a new section “For developers”.

Now, find the following parameters in this section:

• 🔊 "Turn off absolute volume, which is synchronized to the volume of your headphones and your smartphone, and it often solves the problem of low volume on your headphones. 30-50%.
• 🎛️ "Turn off the Bluetooth volume limit (if any) – removes the software limit.
• 📶 "Bluetooth Codecs – Try changing the codec from SBC on AAC or aptX (if supported).

⚠️ Warning: Changing codecs can cause communication problems (crackles, breaks) on cheap headphones. If the sound gets worse after changing the codec, return it. SBC.

If your version of MIUI does not have the option “Disable absolute volume”, try an alternative method via ADB (described in the next section).

3. ADB-Teams: Removing Restrictions Without Root

If the developer settings didn’t help, you can go further and disable restrictions via Android Debug Bridge (ADB). This method does not require root rights, but requires a computer and USB-Suitable for all Xiaomi smartphones, POCO and Redmi on Android 10+.

Step-by-step:

1. Download ADB Tools and unpack the archive in any folder.
2. Enable debugging by USB on your smartphone: Settings → For developers → debugging by USB.
3. Connect the phone to your computer and confirm the debugging permission.
4. Open the command prompt (Win + R → cmd) and go to the folder with ADB:

cd C:\path\do\folder\platform-tools

1. Enter a command to check the connection:

adb devices

If the device is displayed, execute the command to remove the volume limit:

adb shell settings put global bluetooth_hfp_volume 15

This command sets the maximum volume level for HFP-profile (used for calls and multimedia). A2DP-Profile (music) use:

adb shell settings put global bluetooth_a2dp_src_volume 15

⚠️ Attention: Setting the value above 15 It can cause a distortion of the sound on cheap headphones. 12-13 and gradually increase.

After you have completed the commands, restart your smartphone. If the volume has not changed, try to turn off the absolute volume through ADB:

adb shell settings put global bluetooth_absolute_volume_enabled 0

Third-party applications: sound amplifiers

If the software methods didn't work, you can use amplifiers. They work in different ways: some modify system settings, others process sound in real time. We tested 5 popular applications, the results in the table below.

The most effective option is ViPER4Android, but it requires root rights or installation through Magisk.

• 📲 Install the app from Google Play.
• 🔧 Open the settings and activate the option "Ignore Bluetooth Absolute Volume".
• 📈 Move the volume slider above the standard maximum (but no more than that). +6 dB).

⚠️ Attention: Amplifiers add load to the processor, which can lead to:

• 🔋 Faster battery discharge (on the 10-15%).
• 🎵 Distortion of sound at high frequencies.
• 📵 Log delays (lags) when playing video.

5. Hardware methods: cleaning and modifications

If the software didn't work, the problem could be the physical condition of the headphones, and over time, the speakers get dusted and the contacts get oxidized, which lowers the volume on the headphones. 20-40%. Here's what we can do:

Cleaning of speakers:

• 🧹 Use a soft brush (for example, for makeup) or a cotton swab soaked in alcohol.
• 💨 Blow the holes with compressed air (a canister for cleaning equipment).
• ⚠️ Do not use sharp objects – it will damage the membrane!

Leakproofness check:

• 🎧 Put your headphones on and put your fingers against your ears. If the sound gets louder, the problem is the earbuds (they were worn out).
• 🔄 Try to change the sleeves to denser ones (for example, from Sony). WH-1000XM4 It is suitable for many Xiaomi models).

Modification of resistors (for advanced):

In some models (for example, Redmi AirDots), the volume limits the resistor on the board. It can be replaced or shunted, but this is:

• 🛠️ Requires soldering iron and electronics skills.
• ⚡ Risky - if the headphones fail.
• ⚖️ It is not guaranteed (if it is still valid).

💡

Hardware modifications give the most noticeable volume increase (up to 100%), but carry risks. Start with cleaning - it is safe and often solves the problem.

6. Alternative solutions: if nothing has worked

If all of the above methods fail, consider alternative options:

1. Use of an external amplifier:

• 🎛️ Connect your headphones to a Bluetooth amplifier (e.g. FiiO) BTR3K).
• 🔊 The amplifier takes over the sound processing and can increase the volume on the 50-70%.

2. Change of headphone firmware:

Some models (e.g. Xiaomi Air 2) SE) They have alternative firmware from enthusiasts who take the restrictions away. 4PDA or XDA Developers.

Replacement of headphones:

If your model is older than 2-3 years (e.g. Redmi AirDots 2019), it may have worn out its speakers.Modern models (e.g. Xiaomi Buds 4) have better sound systems and fewer volume limits.

4. Xiaomi feedback:

If the headphones are new and the problem is massive, write in support of Xiaomi through:

• 📧 Official website: mi.com/support.
• 🐦 Twitter: @Xiaomi.

Sometimes, after mass complaints, the company releases a firmware update that removes restrictions.

7. Frequent Mistakes: What NOT to Do

When trying to turn up the volume, users often make mistakes that only make things worse, and this is something that is strongly discouraged:

• 🔊 Set the volume to the maximum in the equalizer - this leads to distortion and can burn the speaker.
• 🔧 Disassemble headphones without experience - the risk of damaging the membrane or contacts.
• 📱 Delete system files MIUI In an attempt to remove the restrictions, this will lead to a “brick” (inoperability) of the phone.
• 🔋 Using headphones at max volume for a long time - this harms hearing and reduces battery life.

Also not worth it:

• 💊 Trying to "swipe" headphones through unofficial utilities - a high risk of getting a "brick".
• 🔌 Connect headphones to power sources above 5V (for example, USB 3.0 ports without current limiter).

💡

If after all the manipulations, the headphones got louder, but there were wheezing, return the settings to place. This is a sign that the speakers are not coping with the load.
